What Is Single Sign-On?

Single Sign-On (SSO) is a user authentication process that allows a user to access multiple applications or systems with one set of login credentials. This means that after signing in once, the user can access other interconnected systems without needing to log in again for each one. Single Sign-On (SSO) works by using a central authentication server that all participating applications and services trust. When a user tries to access any of these services, the service requests authentication from the central server. As long as the user is signed into the central server and has appropriate permissions for the application, access is granted automatically without requiring the user to enter additional credentials.
